NILS C. WALLENTHIN, OF ATTLEBORO, MASSACHUSETTS.

PIN.

Application filed December 11, 1911.

To all whom it may concern:

Be it known that I, NILs C. VVALLENTI-IIN, a citizen of the UnitedStates, and resident of the town of Attleboro, in the county of Bristoland State of Massachusetts, have invented certain new and usefulImprovements in Pins, of which the following is a specification.

This invention relates to pins of the type known as cuff or beauty pins,and has for its object to provide a so-called one-piece pin of thinmetal having integral joint cars at one end united at their outer edgesby a web for the purpose of stiffening said ears, rendering it possiblefor them to possess the required strength and rigidity when formed ofthe same thin stock as the rest of the body portion of the pin, and topivotally mount a pin-stem between said ears.

A further object of the invention is to provide one or more arms formedintegral with the edge of the hollow body, and to extend said arm orarms laterally across said body from edge to edge thereof to provide afulcrum for the pin-stem.

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described andparticularly pointed out in the appended claim.

Of the accompanying drawings: Figure 1- is a sectional side elevationshowing a pin of my improved construction. Fig. 2 is an enlarged planView of a blank of the pin body as cut from sheet stock. Fig. 3 is aplan view, greatly enlarged, representing the pin body and fulcrum armsbent up into operative position. Fig. 4- is a section in elevation online 4-4: of Fig. 3 look ing in the direction of the arrows showing afulcrum arm as engaging the inner side of the pin body.

Referring to the drawing, 1 designates the body portion of what iscommonly known as a one-piece beauty pin, which body portion after beingblanked out is bent or swaged up into substantially a U-shape in crosssection. The catch member 2 is formed at one end of the blank and bentup and over to receive the pointed end of the pin stem 3. At theopposite end of the body, two joint Specification of Letters Patent.

ears 4t4 are formed on the blank, see Fig. 2, and are bent up into theposition illustrated in Fig. 4 to receive the head of the pin-stembetween them. When this pin is formed of precious metal it is desired tomake the stock rather thin. I therefore provide a web 5 to join theouter edges of these joint ears to support the same and give them therequired strength when formed of metal the same thickness as that of thebody portion.

The essential feature of my invention is the forming of a fulcrum arm 6integral with the edge of the body portion adjacent to the inner edge ofthe corresponding joint ear, said arm extending laterally across the pinbody to the opposite edge thereof where it may be secured by anysuitable means, but I preferably turn the end 7 of this arm downward tofollow along the inner wall of the body, as illustrated in Fig. 4,whereby this end is supported from the bottom portion of the pin body.The middle or bear mg portion of this arm may, as illustrated in Fig. 4,be bent downward slightly as at 8 so as to accommodate itself to theengaging end 9 of the pin-stem whereby said arm may receive said end toprovide a fulcrum for re taining the pointed end of the pin in its catchmember by spring pressure. I do not wish to be restricted to the formingof this fulcrum with a single arm as another arm 10 may be formed on theopposite edge of the body and adapted to extend across to the oppositeedge thereof to work in c0njunc tion with the arm 7 when desired toprovide a broader or stronger fulcrum bearing for the pin stem.

By my improved construction the whole pin body may be constructed ofvery thin material and all of its members formed integral therewithwhich is of great importance in pins of this character as no heat isthen required for soldering the parts together.

I claim:

A one-piece pin comprising a body portion having substantially a U-shapein cross section, said body having integral joint ears for a pin-stem,and an arm integral at one end with one side edge of the body portionadjacent said ears and extending laterally In testimony whereof I aifixmy signature across to the opposite edge thereof providing in presenceof two Witnesses.

a fulcrum for the pin-stem, the free end of a said arm extendingdownward along the in NILS WALLENTHIN' side of the body Wall to restagainst the bot- W'itnesses:

tom thereof to assist in the support of said HOWARD E. BARLOW,

fulcrum. E. I. OGDEN,
